[Webtest] A new aspect on 'Cannot read property "forms" from undefined ... '?

[Georg1729]

Dear Marc,

thank you very much for your reply. This morning I found out (using FireBug
for Firefox) that indeed there is a JS error on the application side
involved (which I didn't notice earlier since company emphasizes the use of
IE and IE seems to be less sensibel to JS errors). So I apologize for
putting HtmlUnit under suspicion.

I really like the clean concept and good integration of WebTest, the reports
are nice. So, I hope I can circumloculate the problem below somehow.

Regards, Georg
